### Incluir los `APIRouter`s para `users` y `items` { #include-the-apirouters-for-users-and-items }

Ahora, incluyamos los `router`s de los submódulos `users` y `items`:

{* ../../docs_src/bigger_applications/app_an_py39/main.py hl[10:11] title["app/main.py"] *}

/// info | Información

`users.router` contiene el `APIRouter` dentro del archivo `app/routers/users.py`.

		Result  string
		Vars    []interface{}
	}{
		{
			[]clause.Interface{clause.Select{}, clause.From{}},
			"SELECT * FROM `users`", nil,
		},
		{
			[]clause.Interface{clause.Select{
				Columns: []clause.Column{clause.PrimaryColumn},
			}, clause.From{}},
			"SELECT `users`.`id` FROM `users`", nil,
		},
		{
			[]clause.Interface{clause.Select{
				Columns: []clause.Column{clause.PrimaryColumn},
			}, clause.Select{

			"SELECT * FROM `users` FOR UPDATE", nil,
		},
		{
			[]clause.Interface{clause.Select{}, clause.From{}, clause.Locking{Strength: clause.LockingStrengthShare, Table: clause.Table{Name: clause.CurrentTable}}},

### *Operações de Rota* com `APIRouter` { #path-operations-with-apirouter }

E então você o utiliza para declarar suas *operações de rota*.

Utilize-o da mesma maneira que utilizaria a classe  `FastAPI`:
